If you think the Ticketmaster situation with Taylor was a mess... just wait until you try to get to Raymond James Stadium to see the show! Tampa traffic is a monster on a normal day... Now throw in maybe the biggest show to ever hit Tampa. Oh, and if you're driving from Orlando, GOOD LUCK!
A lot of the presale parking is sold out, and they say expect what usually takes an hour to take three. You have a month to figure it out, start with this article from The Tampa Bay Times.
And remember... this is supposed to be fun... so don't stress the traffic... Just Shake It Off.
